Rexroth Frequency Converter EFC x610
Series
Fig. 12-58: Start directly
Set parameter E0.37 'Start frequency holding time' to a non-zero val-
ue when the motor needs to be started with certain start frequency.
DC-braking before start
'DC-braking before start' is used in applications where the load may encounter
forward / reverse rotation when the frequency converter is in stop mode. The
larger DC-braking current, the larger braking force. However, the withstanding
capability of the motor has to be considered before use the DC-braking function.

When [E0.38] ≠ 0, DC-braking will be executed before the frequency convert-

er starting to accelerate to [E0.36] 'Start frequency', the braking current is
decided by [E0.39].
When [E0.38] = 0, the converter starts at the starting frequency.
